一种假设的素粒子

quark
n 1: (physics) hypothetical truly fundamental particle in mesons
and baryons; there are supposed to be six flavors of quarks
(and their antiquarks), which come in pairs; each has an
electric charge of 2/3 or -1/3; "quarks have not been
observed directly but theoretical predictions based on
their existence have been confirmed experimentally"
2: fresh unripened cheese of a smooth texture made from
pasteurized milk, a starter, and rennet [synonym: {quark cheese},
{quark}]

  • Tetraquarks: new configurations of subatomic particles discovered
    Researchers using the Large Hadron Collider at CERN say they’ve recently discovered a new exotic form of subatomic particles called tetraquarks They exist for just fractions of a second, so they’re hard to spot and study But, luckily, University of Cambridge physicist Harry Cliff, is working on the experiment that discovered them, as he described to Chris Smith
